ZTNA Integration

Quality of zero-trust network access integration for replacing VPNs with identity-aware application access.

SASE Platform Completeness

How well the SWG integrates with CASB, ZTNA, FWaaS, and SD-WAN components for a complete SASE architecture.

Top Recommendations

#1
ZscalerBest Cloud-Native SWG

Custom enterprise pricing / Per-user subscription

Zscaler Internet Access (ZIA) is the market leader in cloud-delivered SWG with the largest global cloud infrastructure. Its inline inspection covers SSL/TLS traffic without performance degradation, and the zero-trust architecture eliminates the need for VPNs or on-premises proxies.

#2
NetskopeBest for Data Protection

Custom enterprise pricing / Per-user subscription

Netskope's SWG excels at inline data protection with deep DLP capabilities across web traffic. Its Cloud Confidence Index provides visibility into shadow IT risk, and the NewEdge network delivers sub-10ms latency globally.

#3
Palo Alto Prisma AccessBest for Palo Alto Customers

Custom enterprise pricing / Per-user or per-Mbps models

Prisma Access provides SWG as part of Palo Alto's SASE platform, extending firewall policies to remote users and branch offices. Organizations already using Palo Alto firewalls get consistent security policies across all locations.

Best Secure Web Gateways for Unified SASE FAQ

What is a Secure Web Gateway?

A Secure Web Gateway (SWG) inspects and filters web traffic to protect users from web-based threats and enforce acceptable use policies. Modern cloud-delivered SWGs are a key component of SASE architecture, providing protection regardless of user location.

Do I need a separate SWG or should I use my SASE platform's SWG?

For most organizations, using the SWG built into your SASE platform (Zscaler, Netskope, Palo Alto, Cisco) provides better integration and simpler management. Standalone SWGs only make sense if your SASE vendor's SWG capabilities are significantly weaker.

Is SWG being replaced by SASE?

SWG is becoming a component of SASE rather than a standalone product. Gartner no longer publishes a separate SWG Magic Quadrant, instead folding it into the Security Service Edge (SSE) evaluation. All major SWG vendors now position their products as part of SASE or SSE platforms.
